rails over which the locomotive is passing.

The sand pipes of locomotives are secured 'to the locomotive frame and extend downwardly to deliver sand to the tracks immediately in advance of the foremost drive wheel.

frame has a certain amount of side play with respect to the drive wheels and that this side play increases as the locomotive grows older, the sand pipes are often thrown by the movement of the body with relation to the drive wheels to one side or the other of the track, so that sand is not delivered to the track. This is particularly true during movement of the locomotive about curves and it is at this time that the sanding apparatus is in greatest demand. This relative movement of the drive wheels and locomotive frame is necessary, for obviously if the wheels were rigid with relation to the frame, they would have a tendency to ride over the rails during passage about a curve. An important object of this invention is theprovision of an eX- tremely simple and durable apparatus for correcting the direction of the sand pipes to compensate for relative transverse displacement of the frame and drive wheels so that the sand may be at all times delivered to the track.

These and other objects I attain by the construction shown in the accompanying drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein:

Figure 1 is a fragmentary side elevation of a locomotive showing sanding apparatus controlled in accordance with my invention;

Figure 2 is a transverse sectional view showing the manner in which the control lever engages the sanding pipe and drive wheel;

Figure 3 is a side elevation of the control lever.

Referring now more particularly to the drawing, the numeral 10 generally designates the frame of a locomotive, 11 a front Due to the fact that in all locomotives the Y drive wheel thereof and 12 a sanding pipe extendingdownwardly from the frame over therail adjacent the drive wheel 11 and in ad- Vance thereof. In accordance with my invention, I support from the frame 10, by means of a bracket 13, a lever 14: which is connected to this bracket by a'vertical pivot 15 which engages the lever centrally thereof. The forward end of this lever is provided with an aperture 16 for the passage of the sanding pipe, While the rear end thereof is in a Y- form and has the arms 17 thereof spaced apart a distance closely approximating the width of the drive wheel 12, The arms 17 engaging opposite faces of the wheel 12 cause the rear end of this lever to swing in the path of the wheel, so that the lever shifts about its pivot and by its engagement with e. s ndi gr p fieXes the sanding rip t0 maintain the outlet end thereof in alignment H with the wheel.

Assuming the sanding pipe to be at the right hand side of the locomotive, in passing about a right hand curve, the frame of the locomotive will tend to continue in a straight path and the drive wheels will shift slightly to the left of the body. This shifting of the drive wheels to the left will cause the sanding pipe to move to the right, with the result that it remains in alignment with the track instead of following the path of the body of the locomotive. Upon a left hand curve, the direction will, of course, be opposite to that just described. There is no necessity for changing the sanding pipe 12, as usually applied to a locomotive, as these pipes have sufficient inherent. resiliency to accommodate the displacements to which they are subjected. Due to the simplicity of the construction, it is readily removed or applied u ing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.

I claim 1. In a sanding appliance for locomotives, the combination with the usual locomotive frame, driving wheel and sanding pipe rigidly secured at its upper end to the locomotive frame and depending in advance of the driving wheel, of a horizontally swinging lever pivotally supported from the frame having at its rear end a. fork receiving the wheel the arms of which closely approach opposite faces of the wheel the lever at the opposite side of the pivot from said fork having an opening through which the sanding pipe is directed.

2. In a sanding appliance for locomotives, the combination with the usual locomotive frame driving wheel and sanding pipe rigidly secured at its upper end to the locomotive frame and depending in advance of the driving wheel, of a horizontally swinging lever pivotally supported from the frame having at its rear end a fork receiving the wheel the arms of which closely approach opposite faces of the wheel, the lever at the opposite side of the pivot from said fork having an opening through which the sanding pipe is directed; V the connections of said lever to the frame in-- cluding a bracket rigidly secured to the locomotive frame to the lower end of which the lever is pivoted.

In testimony whereof I hereunto affix my signature.
